1/16"; keep seeds cool and dry, such as in the refrigerator, until sowing. Germinates best when provided with light.
Sow indoors in pots 8 weeks before plantingout. Keep at 35-40°F for 2-3 weeks, then 60-70°F. Alternatively, move trays outside for two to three weeks, then back insidefor germination. If no germination after 4 weeks, chill again.
Direct sow in fall or earliest spring, or wintersow into pots in the shade, covered with a thin layer of clean sand and a wire screen to keep out mice and voles. Check for moisture at regular intervals.
PLACEMENT & CULTIVATION
Angelica has been part of herbal and culinary traditions for hundreds of years, for all parts are aromatic, suggesting licorice and juniper berries. It was an essential ingredient of liqueurs such as chartreuse and hops bitters. Commonly cultivated for the young, tender stems were candied for confections, while dried roots were often used medicinally. Tolerant of shade, particularly in warmer climates, it is an impressive biennial with flower umbels in a starburst form that develops decorative seed heads, adding architectural interest to fall and winter gardens. If desired, remove the flowering stalks right after bloom to encourage their return next spring; however, if left alone, they will self-sow in moist soils to bring years of enjoyment. Beautiful in company with tall russet-hued heleniums mid to back border, where it attracts numerous beneficial insects and pollinators.
About 1" per week, more during prolonged dry weather.
Prefers slightly acidic to neutral but tolerates slightly alkaline soils.
Mix in 2-4" of compost prior to planting. Supplement with an organic granular or liquid feed once in late spring and again in late summer if desired.
